Windows Media Center Extender encountered a DRM failure. Error code: 1, hr: 0x8004b822

Aghhh no Live TV on MCE !!!

For some reason  I started getting the above error today on my meda centre box… after some investigation I killed a mcafee process in the taskmgr. The clue was spotting this error:

An unauthorized window was detected while running the Windows Media Center Experience, ‘McAfee Notification Window’, with file name ‘C:\Program Files\\Agent\mcagent.exe’.
I killed this exe that was running under the MCX2 profile (ensure you have ticked show processes for all users) and suddenly live tv started again,


UPDATE – so the above only worked for a short period  , however today I manged to fix this properly

 I unplugged both (2) TV cards and added one back in , rescanned all the channels and its working again on the extender. I am guessing that one of the TV cards was having issues and this was the one I was connecting to .. hence why it worked briefly as I must have for a short period connected to the working TV Card
